Machining Characteristics of High Strength Thermal Resistant Materials Item Ⅴ, Part Ⅱ Machining Characteristics of Molybdenum-0.5% Titanium Alloy

摘要

A study of the machining characteristics of a molybdenum alloy containing 1/2 percent titanium (Mo-1/2% Ti) has been conducted for turning, face milling, drilling, reaming and tapping operations. The data for the various machining tests is presented in graphical form to show the relationships between tool life, cutting speed, feed, tool geometry, tool material and cutting fluids.nGrinding tests were conducted to determine the effect of grinding wheel grade, wheel speed, down feed, cross feed, and table speed on grinding ratio (G) and surface finish. The data for these studies is presented in graphical form to show G ratio as a function of grinding variables. Results of individual tests including surface finish data are shown in tabular form.nForce measurements were made for turning and drilling the molybdenum alloy. The data is shown in graphical form to indicate the effect of machining variables on unit power, coefficient of friction and tool forces.
